Not yet, the reason we dealt with AD first is that there was more
request for that use case.

We are planning to add FreeIPA<->FreeIPA trusts in due course, and a
kerberos level trust between 2 IPA servers can be done with some manual
work, but there are some details when it comes to providing identity to
the other domain that are missing. (Although SSSD can be configured
easily enough to use 2 separate FreeIPA domains if really needed).
